Summary
TeamDavid Webbox contains an open redirect vulnerability via the 'replyUrl' parameter. An attacker can craft a URL within the application that redirects the user's browser to an arbitrary third-party site. This can be abused for phishing attacks, where users receive a trusted domain link but are redirected to a phishing website.
Risk Assessment
Users may fall victim to phishing, potentially leading to credential theft or malware installation. Trust in the application's domain may be abused.
Recommendation
Update TeamDavid to Rollout 528 or later, where the functionality is disabled by default. Also consider validating redirect parameters in the application.
Other vulnerabilities in TeamDavid
See all- CVE-2026-54217Medium
The TeamDavid Webbox application is vulnerable to a stored XSS vulnerability. An attacker can send an email containing malicious JavaScript code. When a user accesses the email, the stored cross-site scripting is triggered.
- CVE-2026-54205Medium
The link storing functionality in TeamDavid Webbox accepts a 'pathname' parameter with UNC paths, allowing authenticated attackers to trigger outbound connections to attacker-controlled SMB servers. This can expose NTLM authentication information (such as NTLM hashes) and enable SMB relay or credential theft attacks. Exploitation is possible without authentication.
- CVE-2026-54199Medium
TeamDavid Webbox is vulnerable to HTTP header injection through the request body in the link storing functionality (//ServerClient_celink.htm), which is appended to the redirect target in the 302 HTTP response. Adding a line feed allows control over response headers.
Original NVD description (English source)
Tobit Laboratories AG TeamDavid's Webbox contains an open redirect vulnerability via the “replyUrl” parameter. An attacker can exploit this vulnerability to craft a URL within the application that, when visited, redirects the user’s browser to an arbitrary third-party site. This can be abused for phishing attacks, where users receive a trusted domain link but are redirected to a phishing website. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
